3 Claims.

The invention relates to percolator covers provided with transparent tops for observing the action of the percolators, the objects being to improve the construction of such tops, and their attachment to percolator covers, to the end that liquid will not splash between the tops and the walls of the top-receiving openings in the covers, and to the further end that the tops may be inserted through such openings from the insides of the covers, and be securely attached to them.

The invention is illustrated in the accompanying drawing, of which Fig. 1 is a vertical central sectional view through the upper portion of a percolator and its cover; Fig. 2 a partial plan view of the percolator cover; Figs. 3, 4 and 5 vertical central sectional views through the central portions of covers and tops attached to them, illustrating modifications of construction; and Fig. 6 a plan view of the modification illustrated in Fig. 4, showing the top as having been rotated axially to a different position than that shown in Fig. 4.

In the attachment of a transparent top to a percolator cover, the usual practice is to insert the top from above the cover through a top-receiving opening formed in it, the dome of the top being larger than the opening so that the top rests upon and is supported by the margin of the opening. Various means have been provided for removably retaining tops in this position. Be-

cause the tops have been thus attached, their inner ends are necessarily of smaller diameters than the openings through which they are inserted. As a result of this, liquid projected upwardly against the tops and the central portions opening in which there is positioned an integral transparent top, preferably formed of pressed glass, having a dome projecting above the cover, and having a splash-deflecting skirt below the cover and projecting outwardly beyond the wall of the top-receiving opening. By reason of this construction ofthe top, it is inserted in the cover opening from the inside of the cover, thus making it possible to attach a handle to the cover with a small space between the top and the handle. For attaching the top to a cover, the exterior of the top, and the wall of the cover opening through i which it extends, are provided with interengaging elements which may be of various forms and constructions.

Having reference to the embodiment of the in- 6 vention illustrated in Figs. 1 and 2, a percolator l of conventional form is provided with a cover having a central portion 2, and a skirt 3 fitting within the walls of the percolator body. The central portion of the cover is provided with a 10 top-receiving opening l, which, in this case, is bounded by a yieldable flange 5 turned downwardly from the metal of the cover. Within opening 4 there is a top having a dome 5 projecting above the plane of the opening, and a skirt within the cover projecting outwardly beyond the wall of the opening to prevent liquid from splashing between the top and flange 5.

In attaching the top to the cover, it is pressed outwardly from the interior of the cover, sprining flange 5 laterally to permit the dome of the top to pass beyond it. Below the dome B the top is provided with a reduced portion 8 in which flange 5 lies to yieldingly lock the top to the cover. Suitably attached to the cover there is an arch-shaped handle 9, the inner edge of which is relatively close to the top and to the cover, the use of such a handle being made possible by the construction and manner of attachment of the top to the cover.

The embodiment of the invention illustrated in Fig. 3 is the same as that shown in Figs. 1 and 2, with the exception that the top-engaging flange I ll of Fig. 3 is provided with'a plurality of notches H which divide the flange into a plurality of yieldable tines, and accordingly facilitate the insertion and removal of tops.

In the embodiment of the invention illustrated in Figs. 4 and 6, a top I5 is provided with one or more lateral projections I6 which overlie the 40 margin of a flange l1 surrounding the top-receiving opening. When pressing the top through the opening, its lateral projections l6 may themselves form grooves l8 in flange IT, or these grooves may be formed in the flange before the top is inserted. After inserting the top, it is rotated axially to the position indicated in Fig. 6' in which'projections l6 overlie the ungrooved portions on flange I1.

In the embodiment of the invention illustrated i in Fig. 5, the interengaging elements for locking the top 20 to the central portion 2| of a cover are the margin of the top-receiving opening, and a split ring 22, preferably formed of resilient metal, applied to a groove formed on the top adjacent to the base of its dome, the outer portion of ring 22 resting upon the margin of the opening.

In each embodiment of the invention the skirt of the top projects outwardly beyond the wall of the top-receiving opening of the cover, serving the double function of retaining the top in the cover when the latter is turned upside down, and of preventing liquid from splashing between the top and the wall of the top-receiving opening in the cover when the percolator is in use.

According to the provisions of the patent statutes, I have explained the principle and operation of my invention, and have illustrated and described several embodiments of it. However, I desire to have it understood that, within the scope of the appended claims, the invention may be practiced otherwise than as specifically illustrated and described.

I claim:

1. A percolator cover provided in its central portion with an opening, an integral transparent top extending through said opening and having a dome above and a splash-deflecting skirt below and projecting outwardly beyond the wall of said opening, the diameter of said top above said skirt being less than the diameter of said skirt to permit said top to be inserted in said'opening from the under side thereof, and a split ring engaging the side of the top and overlying the the cover.

2. A glass cap structure for closing the opening of a percolator lid, said cap structure comto engage said lid from beneath or below, said spring ring member being adapted to surround the body portion of said cap member and engage said lid from above, whereby said lid is confined between said ring member and the bottom abut-.v

ment portion of said cap member.

3. A glass cap structure for closing the opening of a percolator lid, said cap structure comprising a glass cap member and a spring ring member, said cap member including a body portion and a bottom abutment portion, said body portion being adapted to be inserted into the opening of such a lid from the under side thereof and said bottom abutment portion being adapted to engage said lid from beneath or below, an annular groove in said body portion and said spring ring member being adapted to be received in said groove and to surround the body portion of said cap member and engage said lid from above, whereby said lid is confinedbetween said ring member and the bottom abutment portion of said cap member.
